Fem. Caput nigrum, fronte ferrugined, longitudinaliter sulcatum: 
antenne desunt: prothorax ferrugineo-lanuginosus, lateribus bi- 
tuberculatus, haud dentatus : scutellum ferrugineo-lanuginosum 
lateribus nigrum, glabrum: elytra ferruginea 5-carinata apice 
viv dehiscentia viz truncata: pedes nigri. 
Corp. long. 1°35 unc.; elytrorum lat. max. 5 unc. 
Fem.—Head, including the eyes, black ; the face clothed with fer- 
ruginous down ; epicranium impressed with a longitudinal sulcus, 
which is very deep between the eyes; the eyes are moderately large 
and reniform, the lower or cheek lobe being the largest ; the face has 
a large and deep depression occupying the basal or upper portion of 
the clypeus; the first and second joints of the antenne alone are 
present: prothorax black, clothed with ferruginous down, without 
any trace of that central black velvety vitta which obtains in the 
females of other described species ; the anterior portion of the pro- 
thorax is smooth and somewhat ring-like ; the rest of the dorsal sur- 
face uneven and tuberculated on each side; it has two obtuse tu- 
bercles: prosternum produced between the procoxze into two short 
incurved, backward-directed processes which approximate at their 
apices, leaving an aperture through which the point of a needle may 
be passed: scutellum semicircular, clothed with ferruginous, with 
the exception of the margin, which is glabrous: elytra ferruginous 
and clothed with ferruginous down, wide at the base, narrowing to 
the apex and then truncate, the angles of the truncature being ob- 
tuse; the elytra are carinated, each having five carine ; the first is 
very short and nearly obtuse ; it commences near the scutellum and 
ceases before it has reached a third of the length of the elytron; the 
second and third commence near the base of the wing and unite in 
the apical area; the third and fourth commence almost together just 
below the humeral angle, and unite in the apical area; the two pairs 
are also united, and below their union several other raised anasto- 
mosing lines form a kind of network : the abdomen and legs are black, 
with a short hairy pubescence; metatibize with two distinct apical 
spines. 
sigh Australia. A single specimen of the female, taken by Mr. 
Ince, R.N., in that gentleman’s cabinet. 
Perhaps I may be permitted to avail myself of the opportunity of 
stating that I am assiduously engaged in the preparation of a de- 
scriptive list of the longicorn Coleoptera of our Australian colonies, 
and that I shall feel deeply indebted to any members of the Zoological 
Society who would kindly assist me by the communication of speci- 
mens. As the extent and value of her colonies have always been a 
distinguishing character of Great Britain, so I think should the in- 
dustry of her sons take precedence of other nations in making known 
to the world the abundant riches of those colonies in the field of 
Natural History.
